We study low temperature electron mobility Β΅ n in a GaAs/Al x Ga 1-x As coupled double quantum well structure. Both the extreme barriers are Ξ΄-doped with Si so that the electrons diffuse into the adjacent wells forming two sheets of two-dimensional electron gas (2DEG) separated by a thin central bar
A combined exciton-cyclotron resonance is found in the photoluminescence excitation and reflectivity spectra of semiconductor quantum wells with an electron gas of low density. In external magnetic fields an incident photon creates an exciton in the ground state and simultaneously excites an electro
